Peral Harbor myth #whatever - The Japs copied the attack pattern used by the Brits at the Battle of Taranto. (Battle of Taranto - Wikipedia) Yamamoto was not the first person to think of attacking the American naval base at Pearl Harbor. As early as 1927, war games at the Japanese Navy War College included an examination of a carrier raid against Pearl Harbor. The following year, a certain Captain Yamamoto lectured on the same topic. By the time the United States moved the Pacific Fleet from the West Coast to Pearl Harbor in May 1940, Yamamoto was already exploring how to execute such a bold operation. According to the chief of staff of the Combined Fleet, Vice Admiral Fukudome Shigeru, Yamamoto first discussed an attack on Pearl Harbor in March or April 1940. This clearly indicates that Yamamoto did not copy the idea of attacking a fleet in its base after observing the British carrier raid on the Italian base at Taranto in November 1940. After the completion of the Combined Fleet’s annual maneuvers in the fall of 1940, Yamamoto told Fukudome to direct Rear Admiral Onishi Takijiro to study a Pearl Harbor attack under the utmost secrecy. After the Taranto attack, Yamamoto wrote to a fellow admiral and friend stating that he had decided to launch the Pearl Harbor attack in December 1940.
